Thailand's Construction Materials Index Reaches Record High Due to Persian Gulf Regional Tensions
Thailand's construction materials price index rose to its highest level in 44 months in December 2024, reaching 108.7 points. The 3.2% increase from the previous month occurred against the backdrop of escalating geopolitical tensions in the Middle East, which led to a sharp spike in oil prices and more expensive logistics. According to Thailand's Ministry of Commerce, cement (+4.8%), steel reinforcement bars (+6.1%), and insulation materials (+3.7%) experienced particularly strong price increases. For villa buyers in Na Jomtien and other coastal areas of Pattaya, this means revising budgets for construction and purchasing ready-made housing.

Why the Middle East Crisis is Hitting Thai Construction
Thailand imports approximately 68% of its crude oil from Persian Gulf countries. When the price of Brent crude jumped from $84 to $96 per barrel in October 2024 due to attacks on oil terminals in the Red Sea, maritime transportation costs rose by 41%. Container lines redirected routes to bypass the Suez Canal, which added 12-15 days to delivery times and increased freight rates from $2,200 to $3,100 per TEU on the Europe-Asia route.
Cement plants Siam Cement Group and TPI Polene were forced to raise wholesale prices by 180-220 baht per ton already in November 2024. Reinforcement steel became more expensive due to rising coking coal costs, which Thailand purchases from Australia and Indonesia. Australian suppliers linked prices to oil quotations, triggering a chain reaction.
How Geopolitics Affects Construction Timelines
Delivery delays directly impact project completion schedules. Villa developers in the Na Jomtien area report postponing project completion by 3-5 months. Baan Dusit Pattaya View company, building 18 villas near Dongtan Beach, announced postponing completion from March to July 2025 due to delayed shipments of ceramic tiles from Italy and Grohe sanitary ware from Germany.
Developer Pattaya Prestige Properties recorded an increase in construction budget for one 220 m² villa from 8.2 to 9.1 million baht. The difference of 900,000 baht consists of more expensive construction materials (+520,000 baht), increased worker wages (+180,000 baht), and higher design work costs (+200,000 baht).
Which Materials Have Become Most Expensive in 2024-2025
Analysis of data from the Federation of Thai Industries Construction Club for the period from October 2024 to January 2025 shows uneven price growth across categories.
Steel Products and Reinforcement
Steel reinforcement bars with a 12 mm diameter increased from 18,500 to 19,630 baht per ton (+6.1%). H-beam steel profiles became 5.4% more expensive. The reason is rising iron ore prices in China from $115 to $128 per ton amid reduced exports from Australia.
Cement and Concrete Mixtures
A 50 kg bag of Portland cement rose from 185 to 194 baht (+4.9%). Ready-mixed concrete grade C25/30 increased from 2,100 to 2,180 baht per cubic meter. Manufacturers explain the growth by fuel oil prices, which is used in cement kilns.

Finishing Materials
Imported porcelain tiles became 8-12% more expensive depending on country of origin. Italian Atlas Concorde tiles rose from 1,850 to 2,070 baht per square meter. Spanish Porcelanosa increased from 2,200 to 2,420 baht. Thai manufacturers Cotto and Sosuco raised prices more modestly - by 3.5-4.2%.
Premium sanitary ware (Grohe, Hansgrohe, Villeroy & Boch) increased by 6-9%. A Grohe Eurosmart faucet that cost 8,900 baht in August 2024 sells for 9,650 baht in January 2025.
Villa Price Forecast for Na Jomtien for 2026
CBRE Thailand analysts forecast growth in the average cost of ready-made villas in the Na Jomtien coastal zone by 7-9% by the end of 2025 and another 4-6% in the first half of 2026. A villa with an area of 200-250 m² on a 300-400 m² plot, which cost 10.5-12 million baht in early 2024, could reach 12.8-14.2 million baht by mid-2026.
Price Pressure Factors
Besides construction materials, several additional factors affect costs. Skilled construction worker wages increased by 8-12% over the year. An experienced mason in Pattaya earned 650-700 baht per day in 2023, now requests 750-820 baht. Electricians and plumbers raised rates from 800 to 920 baht per shift.
Land costs in the Na Jomtien area, especially within a 1-1.5 km radius from the coastline, rose from 35,000-42,000 baht per square wah to 44,000-51,000 baht. A villa plot of 100 wah (400 m²) became more expensive by 900,000-1.2 million baht over two years.
Segments with Highest Growth
Villas with pools from 8 meters and sea views show the strongest price growth - up to 11% for 2024. Properties in gated communities with security and common infrastructure (fitness, playground) increased by 8.5-9.2%. Detached villas without additional amenities became more expensive more modestly - by 5.8-6.4%.
Projects with European architects and interior designers demonstrate a market premium of 15-22%. A villa from Orbit Design Studio costs 1.8-2.4 million baht more than a similar-sized one from a local architect.
Developer Strategies Under Rising Costs
Developers apply several tactics to maintain project margins. Some companies switched to Thai alternatives to imported materials. Instead of German Braas tiles, they use SCG Monier products, saving 180-240 baht per square meter of roofing. Instead of Italian Marazzi tiles - Thai Cotto d'Este, which gives a difference of 400-650 baht per square meter.
Other developers conclude long-term contracts with suppliers, fixing prices 9-12 months ahead. Eastern Seaboard Properties company contracted 450 tons of reinforcement in September 2024 at a price of 18,800 baht per ton, which is 830 baht below the current market price.
The third strategy is increasing construction time and stretching the procurement schedule. Instead of bringing in all materials at the start of construction, developers purchase in batches, hoping for stabilization or price reduction. The risk is further growth and even greater costs.
Changing Layouts to Optimize Costs
Some projects are reconsidering architectural solutions. Villa areas are reduced from 180-200 m² to 160-175 m² while maintaining functionality. Two-story houses are replaced with single-story ones, saving on floors and staircases. Open terraces are reduced from 40-50 m² to 30-35 m².
Pools have become shallower: instead of standard 3×8 meters with 1.5 m depth, they build 2.5×7 meters with 1.2 m depth. Savings on concrete and tiles amount to 180,000-220,000 baht per property.
What This Means for Buyers in Pattaya
Russian-speaking buyers planning to purchase a villa in Na Jomtien in 2025-2026 should consider several practical points.
Buying at the foundation or excavation stage now carries increased risk. The developer may include material prices in the estimate as of the design date, but by the time of purchase they will have risen. If the contract doesn't have a clear fixation of the final cost, the developer has the right to demand additional payment. Check the clause about the possibility of price revision - the wording "in case of changing market conditions" gives the developer carte blanche.
Ready-made villas or properties at the finishing stage are preferable. The price is fixed, risks are transferred to the seller. The difference between the cost at the foundation stage and the finished property has decreased from the traditional 15-18% to 8-11%, making the purchase of ready-made real estate more advantageous.
If you still choose a property under construction, require inclusion in the contract of a price fixation clause with an allowable deviation of no more than 3%. Insist on phased payment tied to actual work progress, not calendar dates. This protects against a situation where you've paid 70% of the cost, but the property is 40% ready.
Pay attention to the specification of materials in the contract. The wording "ceramic tiles of European quality" means nothing. Require specification of specific brands and articles: "Cotto d'Este tiles, Kerlite collection, article 5Plus, size 100×300 cm." This excludes replacement with cheap alternatives.
For investors considering villas for rental, the price increase of 8-11% for 2024-2025 is compensated by increased rental rates. A three-bedroom villa in Na Jomtien in the 2023/24 high season rented for 85,000-95,000 baht per month. The 2024/25 season shows rates of 98,000-112,000 baht. Growth of 15-18% outpaces purchase appreciation.
Buyers from Russia should consider exchange rate fluctuations. At the current rate of 0.36-0.37 baht per ruble, a villa for 12 million baht will cost 32.4-33.3 million rubles. If the rate weakens to 0.33 baht per ruble, the same villa will cost 36.4 million rubles. The risk can be hedged by buying baht in advance or opening a multi-currency account in a Thai bank.
Alternative Areas with More Stable Prices
Buyers frightened by price growth in Na Jomtien can consider neighboring areas. Huay Yai, located 15 km from the coast, offers villas 18-24% cheaper. A 200 m² property with a 400 m² plot costs 8.5-9.8 million baht versus 11.2-13.1 million in the coastal zone.
Ban Amphur, an area between Pattaya and Rayong, shows price growth of only 4.2% for 2024. Proximity to Eastern Seaboard industrial zones makes the area attractive for long-term rental to expats working in international companies.
Sattahip, a naval base and developing city 25 km south of Na Jomtien, offers villas for 7.2-9.5 million baht. Infrastructure is inferior to Pattaya, but proximity to the new U-Tapao airport and Eastern Economic Corridor development plans make the area promising for long-term investments.
When to Expect Stabilization of Construction Material Prices
Analyst forecasts diverge. Optimists from Kasikorn Research Center expect stabilization of the construction materials index in the second quarter of 2025, provided conflict de-escalation in the Middle East and oil prices returning to $80-85 per barrel. In this scenario, villa prices in Na Jomtien will increase another 3-4% in 2025 and stabilize in the first half of 2026.
The pessimistic forecast from Siam Commercial Bank assumes a protracted conflict and oil prices remaining above $90 until the end of 2025. The construction materials index will continue growing at a rate of 1.5-2% per quarter. Villas will become 9-12% more expensive in 2025 and another 6-8% in 2026.
The Bank of Thailand's baseline scenario is moderate growth of 5-7% in 2025 with a slowdown to 2-3% in 2026. This forecast accounts for gradual recovery of supply chains and developers' adaptation to new pricing realities.
Conclusions: How Buyers Should Act Right Now
The current situation requires balanced decisions from villa buyers in Na Jomtien. Postponing a purchase in hopes of price reduction is risky - the probability of further growth of 6-9% in 2025 is higher than a correction.
Priority should be given to ready-made properties or construction at the final stage. Saving 8-11% on purchasing an unfinished property doesn't compensate for risks of delays, additional payments, and material replacements. Fix all specifications in the contract with indication of specific brands and articles.
For investors, rental rate growth of 15-18% compensates for purchase appreciation. The payback period for a villa for short-term rental remains at 12-14 years, which is acceptable for the Thai market.
Monitor oil price dynamics and news from the Middle East. Conflict de-escalation could lead to a correction in construction material prices by 3-5% within a quarter, providing a window of opportunity for purchase.
